Letters Patent No. 96,638, dcted-November 9-, 1869.

The Schedule referred to in these Letters Patent and making part of the same:

To'a-ll whom it may concern thereof, which will enable others skilled in the art to.

make and use the same, reference being bad to the accompanying drawings, forming part of this specification.

The object of this invention is to provide an improved machine for shaping and compressing the soles of boots and shoes, after they are fastened to the up pers. The invention comprises a. method of compression by rolling the soles between a lastand former, of peculiar construction, specially adapted for action upon all parts of the soles, whether of similar-form orvarying thickness, as hereinafter more fully specified.

Figure 1 represents-a side elevation of my improved machine, one of the housings of the frame being re- 11'1 oved;, and

Figure 2 represents a section at right angles thereto, taken on the line a: a; of fig. 1.

Similar letters of reference indicate corresponding parts.

verscly, and arranged to be readily applied to or taken from a rocker, 15, with the bottom upward.

The rocker is connected to a shaft, (J, having suitable beariugs in a cross-head, I), supported betweentwo -shapcd housings, E, and connected, by rods F,

to a similar cross-head, G, above the top of the houslugs.

This shaft 0 is provided with a large segmental wheel, H, which gears with a train operated by a crank-shaft, or other suitable means for imparting an oscillating movement. p v

1 represents a former, designed fi)r 'orking against the bottom of the last. It is concaved incross-section, to fit t'he convexity of the last, and convex longitudinally for the most part of its length, for fitting the longitudinal concavity of the-last bet-ween the ball and heel, but slightiy concave at the heel, and the same to a greater extent from the ball of the last to the toe.

. This former is suspended by pivots, a, at each end, from rocker K, suspended in hearings from the upper housing G, and is free to oscillate on these pivots to some extent.

The rear end is provided with a bracket, b, sup porting a set-screw, d, for gauging the position-0f the last relatively to the former.

. The curvatures of the former in the direction of the length, both convex andv concave, are so calculated, relatively to the shape of the bottom of the last and radii of the two centres of motion, that when A represents a last, having a convex bottom transthe two are rocking back and forth together, the former will press on all parts of the bottom alike.

The upper cross-head G is provided with yielding \v'ashers, L, between it and the binding-nuts M, of the rods 1 which allow-the cross-head to yield to 'any thick and hard places in the sole.

After the soles are secured to the uppers, the boots or shoes are placed on the last, the said last being oscillated so far forward as to disengage it from the former. They are t en brought together by moving the last back, so the. theheel strikes the set-screw d, which governs the position of each relatively to the other. 'The to-and-fro oscillating motion is then im parted by turning the crank back and forth, as long as required, producing a rolling-compression on-the sole, which reduces it tb an even thickness, and levels the uneven places very rapidly, and with but little labor.

The pivots a. permit the former to oscillate laterally, to accommodate itself to any parts where one side of 'the sole may have thicker places than the. other, while, 'atthe same time, acting upon the whole surface transversely.

The top of the last is considerably enlarged at, the point where it is seated on the rocker B, and one or more dowel-pins may be used toholdthc parts in line. with ea -l| other.

This 'oint may, if preferred; or found best, be so madcas to permit the last to have a lateral oscillation, to' harmonize with the lateral oscillation of the former.

Having thus described'my invention,

I claim as. new, and desire to secure by Letters Patentl. The combination, with a last, arranged 'to-oscih late as described, of a former, oscillating in unison therewith, and against the face thereof,and provided with a longitudinal convexity, fitting the hollow of the lastwhen oscillating thereon, and concavities at the ends, fitted to work upon the heel and toe of the said last, substantially as specified.

2. The combination of the same, when the former is concaved transyersely, and arranged to oscillate on its longitudinal axis, and the face of the last is made convex, to correspond therewith, substantially as specified.

3. The elasticwaShers L L, arranged on the rods F 1*, between the cross-head G and binding-nuts M M, to operate in conjunction with the rocker and former I, as shown and described.

4. The combination of the rocker B anl last A, substantially as specified.
